Mm Patent No. 68,014, dated August 20, 1867 IMPROVEMENT IN PUMPS.

TO ALL WHOM IT MAY CONCERN; 7

Be it known that we,'C. Yanmacn and D. JLLucm, of Quincy, in the county of Adams, and State of Illinois, have invented a new and improved Pump; and we do hereby declare that the following is. a full, clear-,1.

and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming'part of 'this specification.

This invcntionrelates to certain improvements. in the construction of pumps, whereby-the same are made si pler. and oper better l c th pumps now in general use. In the annexed drawings our invention is illustrated- I Figure 1 being a longitudinal vertical section of our improved pump.

Figure 2 is a vertical cross-section of the same, taken on the line a: z, fig. 1.

Figure 3 is an inside face view of one of the cylinder-heads.

Figure 4 is a detached side view ofifthe same.

Figure-5 is a. face view of the packing botweenthe cylinder and cylinder head.

Figure '6 is a verticalcross-section of the piston, I i

Figure 7 is. a vertical longitudinal section of the same.

Similar letters of reference indicate like parts.

A is a horizontal cylinder, open all both ends, and pro vided with chambers B and G at its top and bottom respectively, said chambers being also open at both ends. I) D are the cylinder-heads, which are provided with holes at the ends of the chambers A, B, and G, establishing communication between the same. Between the ends of cylinder and the heads .ire placed indie-rubber plates or packings E, which are perforated at the ends of'the cylinder 4, and which are out, at the ends of the chambers B and C, so as to leave four valves a,,b, c, and d,.as shown in fig. 1. These valves are part of the rubber plates E, their lower and side edges heing cut'out, while their, upper edge is not cut, and acts as a hinge for the valveto swing on, as shown in fig. 5. The vlalyes are weighted metal plates e e, which are attached to the inside of the suction-valves a and d, and to the outside of the discharge-vdlves 6 angle, as shown. F is the supply pipe connecting with the chamber.B, and G is the discharge .pipe connecting with the chamber 0, as shown in fig. 1, H is an air-chamber, attached to andconmeeting with the discharge pipe, as shown. For the suction-valves a and (Z arepro'vided seats f in the form of projecting tapering flanges, which are part of the cylinder, and for the valves 6 and 0 similar seats 9 are arranged. on the heads D, as shown in figs. 1, 3, and 4. I is the piston attached to a piston-rod, K, which is operated by an oscillating lever, L, pivoted to a stationary horizontal beam, M, or by any other. suitable device. The rod K passes through packing N, on which a. lubricating device, It, is arranged, as shown. The piston is formed of a metal ring, 2', placed upon a solid collar, Z, on the rod, and held between two flanges m and 'n, of which the latter is held in place by a nut, a, as shown in figs. 1 and 7. The ring i is cut obliquely, 'as shown,- so as to form a-spring. It is provided with two-( more or less) grooves around its rim, into which leather or other flexible rings 12 are placed, said r'mgs p being, by means of the spring 2', pressed close against the inner surface of the cylinder, whereby a water-tight packing is efi'ected.

Having thus described'our invention, what we claim asrrew, and desire to secure by Letters Patent, is

The cylinder-heads D, constructedas described, providedwith the projecting inclined flsngeg upon their upper sides, fitting over the upper side of the cylinder A, the letter provided with corresponding inclined projecting flangef upon its lower side, fitting into the lower part of the heads D, all arranged as descrilbed, whereby the said heads D are prevented from having any vertical movement independently of the cylinder, as herein shown and described. VERHIAUD,

. D. J. LUCIE.
